Multilumen connector to multiple individual tubing

A method of manufacturing an umbilicus for use in an umbilicus-driven fluid processing system, comprising:

• providing an elongated umbilicus body having first and second ends and defining at least one fluid-transmitting lumen extending therebetween;
• providing a first end fitting defining an interior cavity having a flared portion and a bore communicating with the inner cavity;
• inserting the first end of the umbilicus body within the bore and fixedly attaching the umbilicus to the first end fitting;
• inserting an adapter including a tapered portion into the cavity with the tapered portion received within the flared portion of the interior cavity, the adapter having at least one port extension extending into the fluid transmitting lumen of the umbilicus body, and the adapter including a lumen extending through the port extension and communicating between the at least one umbilicus lumen and a tubing port defined in the adapter, the adapter and end fitting including interfering surfaces to enhance torque resistance therebetween, and connecting an individual tube to the tubing port of the adapter.

A pre-assembled disposable centrifugal processing fluid circuit including a centrifugal processing chamber for rotating within the centrifuge and an umbilicus communicating at a first end with the centrifuge chamber and being configured at a second end for securing to a non-rotating portion of a centrifuge, wherein the umbilicus body includes at least one fluid-transmitting lumen extending between the first and second ends;

• a first end fitting defining an interior cavity and including an elongated bore communicating with the cavity;
• the first end of the umbilicus body extending into the bore and being fixedly attached to the fitting;
• the interior cavity of the first end fitting includes a flared portion;
• an adapter including a tapered portion received within the interior cavity of the first end fitting with the tapered portion received within the flared portion of the interior cavity, and having at least one port extension extending into the fluid transmitting lumen of the umbilicus body;
• the adapter including a lumen extending through the port extension and communicating between the at least one umbilicus lumen and a tubing port defined in the adapter and configured for attachment to an individual flow tube;
• and
• the adapter and end fitting including interfering surfaces to enhance torque resistance therebetween.
